Answer / scorpio
Take one ball from machine 1, 2 from machine 3 and so on
until machine 20. If none of the machines are defective then
you the weight will be 210 grams. Since one of the machine
is defective, you'll get 100 gms less for all the balls from
that machine.
So, if the weight is 100gm less then machine 1 is defective,
if 200gm less then machine 2 is defective and so on.. you
get the idea.
BTW, a cool trick to find the sum of the sequential numbers
starting with 1 like above (1 to 20) is [multiply by half
then add half]
20*(20/2) + 20/2
Enjoy..
